Gets the viewport bounds.
The lower left and upper right corners of the rectangle determine the orientation of the measuring coordinate system (that is, the direction of the positive x and yaxes) in this viewport, which may have a different rotation from the page.
The viewport bounds are defined in the same coordinate system like the page media box and crop box.

Gets the COS viewport.

Gets the viewport measure.
The measure specifies the alternative coordinate system for the viewport. It provides the information needed to convert coordinates in the page's coordinate system to coordinates in the measuring coordinate system.

Gets the viewport name.
